Its obvious
The peasants in AOS to here
But not ALL of them just like 2 or 3 for each race because ALL races need these or at least most races(undead, scaledfolk,and orcs might not need these)
Same stats but different appearance due to different races

Maybe changing the mechanics of people and some simple units will appear from the peasants, that is, a peasant is made in 1 turn, and he can be converted into a swordsman, archer, and so on in 1 or 2 turns

Doesn't seem so bad being that elves don't have health upgrades so I guess it makes sense. (Also she can heal herself with lembas wich might heal her all the way being that I doubt her health will be very high.
